SPECIFICATION forming part of Letters Patent No. 565,648, dated August 1 1, 1896.

Application filed April 1 6, 1 8 9 5.

To all whom it .may concern.-

Be it known that I, WILLIAM F. TROAST, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State In the accompanying drawings, which form a part of this specification, Figure 1 is a rear face View of the lock, the back plate being removed and showing the bolt in its normal position; and Fig. 2, a similar view, but showing the bolt in a retracted position. Fig. 3 is a rear face view of the interior of the lockcase, the operating mechanism being removed and the stem of the handle shown in section. Fig. 4 is an inner perspective view of the handle. Fig. 5 is a vertical section on broken line 5 5 of Fig. 1. Fig. 6 is a rear face view of a portion of the interior of the lock, parts being cut away. Fig. 7 is a section on broken line 7 7 of Fig. 2. Fig. Sis an inner face view of the back plate, showing the key-guide engaged therewith but not secured in place; and Fig. 9, a similar View showing the keyguide fastened in the back plate. Fig. 10 is a side view of the key-guide detached; Fig.

11, a similar view showing the key-guide engaged with the escutcheon and the back plate, the latter being in section; Fig. 12, a vertical section of the same, showing the key-guide engaged with the back plate but not secured therein; and Fig. 13, asimilar View, but showing the key-guide fastened in the back plate. Fig. 14 is an outer face view of the escutcheon; Fig. 15, an inner face view thereof; Fig. 16, a face View of the keeper and the guardplate; Fig. 17, an outer end view of the keyguide, showing the cap thereon; Fig. 18, a vertical section of the escutcheon, the washer being in place but not secured; and Fig. 19,

Serial No. 545,858. (No model.)

a similar view of the escutcheon, showing the washer fastened therein and the key-guide engaged with the escutcheon. Fig. 20 is a face View of the key.

Referring to the details of the drawings, A indicates the body of the case, which has an elongated slot at in the front plate A thereof, the ends 0. of said slot being circular and of greater diameter than the width of the intermediate part a, as shown in Fig. 3.

B is a handle, 13 the guard-plate formed therewith, and B the stem of the handle. The butt or inner end of the stem plays in slot a a, and it is flattened on opposite sides Z) thereof, so that the diameter between those sides is such as to permit it to. engage and slide in the part a between the circular ends a; but the sides 1), between sides b, are convex or rounded, and the diameter of the butt through them is greater than the width of slot a and such as to permit the butt to revolve in circular ends a, so that when said butt is in ends a and the handle is turned with the sides I) at right angles with the sides of slot at the butt is locked in ends a thereof. Section 12 of stem 13 engages and is revoluble in an opening in bolt D, adapted to slide longitudinally in the case, as is usual with this class of locks. Section b of the stem passses through a thin plate, E, .80 which plays longitudinally thereon and is adapted to rest on the bolt. A similar plate E engages, and is rigidly secured to, the outer end, 13 of the stem, a spring E being coiled around section 1) thereof and having 8 5 its ends bearing against plates E and E. In the face of bolt D, adjacent to plate E, are formed two elongated recesses cl (1, radiating at right angles with each other from stem 13 and constructed to be engaged by a springfinger e on plate E. Finger eis formed'with plate E, and is of spring metal and normally bent outward from said plate, as shown in Fig. 5. Then the handle is turned with the sides I) of the butt parallel with the sides of 5 slot 0., finger e is engaged with recess (1, and when the handle is turned with said sides I) perpendicular to the sides of slot at the finger engages recess d. The sides of recesses d d and of the finger are beveled, as shown, IOO

so that said finger may be disengaged from.

the recesses by turning the handle. The finger is held in engagement with the recesses by the pressure of spring E on plate E and prevents the accidental turning of the handle, to which positive force must be applied to disengage the finger from said recesses. The revolution of the handle is limited in one direction by the engagement of finger c with a stud d on the bolt and in the other direction by the engagement of a shoulder c on plate E with said stud, as seen in Fig. 6.

In the back plate A a circular opening is formed opposite the tumbler A which has an arm A thereon, adapted to engage a shoulder D on the bolt and retract the same, said tumbler being turned by the engagement of studs K on the end of key K with a rib D of the tumbler. The opening in back plate A is engaged by the inner end of a key-guide F, divided longitudinally into sections and having inside thereof suitable wards F. Near the inner end of thekey-guide is formed a collar F which bears against the outer face of the back plate; and outside of said collar is an annular flange F which engages the opening in the back plate and is adapted to be riveted or expanded over the rim of said opening, as illustrated at F, Figs. 9, 11, and 13. On flange F are studs f, adapted to engage notches a in the opening in the back plate to prevent the key-guide from turning therein.

In the sides of the key-guide are formed one or two recesses f near its outer end; and that end of the key-guide is. embraced by a cap G, secured thereto by indentingthe metal of said cap, so that the teats g, formed by such indenting, engage recesses f. This cap may be of any depth necessary to properly bind the key-guide sections together.

The cap itself fits into a socket on the escutcheon II. This escutcheonis externally of the ordinary construction, and is secured to the door in the usual manner; but on the inner face of the escutcheon and around the key-opening H is formed an annular bearing h, and around the bearing is an annular shoulder h, around which, again, is a rim 72. In the socket formed by shoulder h is located a revoluble guard-plate M, having the usual key slot or opening m; and on the shoulder there rests a ring or annular keeper N, the inner edge of which laps the guard-plate. The keeper is secured in place by riveting over rim 71 and cap G bears against the face of said keeper within the socket formed by riveted-over rim 77. as shown in Fig. 1.). This construction for securing the guard-plate is simple and cheap, and both holds said plate firmly in place and yet allows it to be turned with perfect freedom.

I do not confine myself to the details of construction herein shown and described, as it is obvious that many changes may be made therein without departing from the principle and scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
